Due to limited normative studies, there is no optimal mVEMP protocol to be implemented\n clinically. Apart from the conventional electrode configuration, a na\u00efve montage referred to as the forehead reference has been used in recent studies. Purpose:<\/jats:bold> This study compared latency and amplitude parameters of mVEMP between the zygomatic and forehead electrode\n configurations to address the optimal electrode montage to elicit mVEMP. Research Design:<\/jats:bold> Cross-sectional research study. Study Sample:<\/jats:bold> Thirty healthy participants (mean age: 23.3\u2009years; 14 males and 16 females). Data Collection and\n Analysis:<\/jats:bold> Participants underwent mVEMP testing under two-electrode montage conditions (zygomatic and forehead reference electrode montages). Results:<\/jats:bold> Statistically significant increases in P1 latency, decrease in N1 latency, reduction of P1-N1 interpeak interval,\n enlargement of both unrectified and electromyography-rectified amplitudes, and lower interaural amplitude asymmetry ratio were observed for the forehead electrode montage compared to the conventional zygomatic montage. Conclusions:<\/jats:bold> mVEMP response waveforms obtained using\n forehead reference electrode montage are superior to the zygomatic montage. Hence, the forehead montage is suggested for further research on mVEMP.<\/jats:p>","DOI":"10.3766\/jaaa.240100","type":"journal-article","created":{"date-parts":[[2025,5,27]],"date-time":"2025-05-27T02:05:32Z","timestamp":1748311532000},"page":"180-187","source":"Crossref","is-referenced-by-count":0,"title":["Optimal Electrode Configuration for Masseter Vestibular-Evoked Myogenic Potential: A Comparison Between Zygomatic and Forehead Electrode Montages"],"prefix":"10.3766","volume":"36","author":[{"given":"Aishwarya","family":"Nagarajan","sequence":"first","affiliation":[{"name":"*Department of Audiology, All India Institute of Speech and Hearing, Mysore, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sujeet Kumar","family":"Sinha","sequence":"additional","affiliation":[{"name":"\u2020Center of Excellence for Persons with Tinnitus and Vestibular Disorders, Department of Audiology, All India Institute of Speech and Hearing, Mysore, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2087","reference":[{"issue":"(3-04)","key":"c1","first-page":"58","article-title":"Masseter vestibular-evoked myogenic potential result of possible Meniere\u2019s patients","volume":"35","year":"2024","journal-title":"J Am Acad Audiol"},{"issue":"(8)","key":"c2","first-page":"1635","article-title":"Vestibular evoked potentials in human neck muscles before and after unilateral vestibular deafferentation","volume":"42","year":"1992","journal-title":"Neurology"},{"issue":"(3)","key":"c3","first-page":"691","article-title":"How does high-frequency sound or vibration activate vestibular receptors","volume":"233","year":"2015","journal-title":"Exp Brain Res"},{"issue":"(9)","key":"c4","first-page":"1511","article-title":"Vestibulo masseteric reflex and acoustic masseteric reflex.
